' To aZZ whom it may concern:

Be it known that I,` WILLIAM T. CARROLL, of Worcester, county otVorcester, and State of Massachusetts, have invented an Improvement in Spindle Supports for Spinning- Frames, of which the following description, in connection with the accompanying drawings, is a specilication, like letters on the drawings representing like parts.

rlhis invention has for-its object to simplify and cheapen the construction ot' spinning-maate the employment of nuts and screws, and of' a loose bolster in a bolster-case, I have directly combined with the bolster or step rail, at suitable intervals apart, vertical pins or studs which serve as the pivots for the spindle-supports, the latter serving both as bolsters and steps, the spindle-supports, as herein shown, being made as blocks, each block having an upright tube or sleeve to receive thepintle of the spindle,'each block being pivoted loosely with relation to the step-rail at one side of the upright tube or sleeve in which the pintle of the spindle is made to enter and rotate, the upright tube constituting the entire lateral bearing for the pintle of the spindle.

Figure 1 represents a spindle-support or bolster-bearing and step-rail embodying my invention, thesleeve-whirl, spindle-support,and rail being in section. Fig. 2 is a plan or top view, on a smaller scale, of a part of a bolster or step rail with one of my improved spindlesupports set loosely on the said rail, and Fig. 3 is a modification to be referred to.

The step-rail Ais herein shown as a narrow plain rail, having at its edge projections or lugs A', which, as herein shown, receive and hold pins or studs B, which serve as the pivots for the spindle-supports. Each spindler,support is composed of a block, C, having at one end a tubular or sleeve-like upright, O,to

receive the pintle a of the spindle l), herein shown-as provided with a sleeve-whirLa, ofv usual constructiomthe said block at itsV other end having'an upright, C, provided with a socket to oe entered loosely (see Fig. l) by a pin or stud, B, the diameter of the socket in the said upright portion C2 being enough larger in diameter than the diameter of thel pin or stud B to constitute a loose t of one with relation to theother, so that the block may move laterally for a slight extent inany direction on the rail A, as the foot of the spindle moves or ti ps` owing to high speed or unequal loading of the spindle. The upright O'l and the main part ot' the block G are bored orprovided withcommunicating channels for the passage ot oil into the interior of the up- 4right C', in whichthe pintle of the spindle' rotetes. A

In Fig. l I have shown the pin or stud B as fixed to the rail A, and entering looselya socket in the spindle-support C; but it is obvious that the same effect would be gained by providing the rail with a hole and lixing the pin or stud to the spindle-support, as in Fig.

3, at one side of the sleeve or tube C, in whichl the pintle ofthe spindle rotates, the said pin or stud entering loosely a hole in the rail.

My invention will not be departed from if the pin or stud Breferred to were surrounded in the socket or holel in which it enters with a piece of elastic tubular packing or other equivalent cushion.

The spindle-supportherein described intended to hold the pintle of a top spindle in a yielding manner, and to obviate the employment of usual bolster-cases having in them loose bolsters surrounded by elastic packing,

'or by oil, to act as a cushion, as heretofore commonly used. l

The spindle-support is restrained from rotating to too great extent by a suitable pin or projection, 12, herein shown as fixed in the rail and entering loosely a hole in the support; but the pin or projection may be carried by the support and 'enter loosely a hole in the rail.

IOO

I do notbroadly claim a spindle-support pivoted on a pin or post erected in a block resting upon the upper side of the rail.

5 l. A spindle, a bolster or step rail, and a pin or stud, one end of which enters a hole in the said rail, While its other end terminates above the said rail, combined with a spindlesupport consisting of a block having not only o an upright sleeve to receive the pintle of the spindle, but also a socket to surround the said pin or stud loosely, thereby permitting the block to move to a limited extent above the surface of the said rail with the pintle or lower 5 end of the spindle, substantially as described.

face of the said rail with the pntle or lower end of the spindle, the said block having coinmnnicating passages for oil, substantially as described.

3. The combination7 substantially as described, of the bolster or step rail, the spindie, the spindle-support having at one end a sleevev or tube to receive the pintle of the spindie, and a pin or` stud directly bntloosely connecting the said support and rail, and loc-ated out of linewith or at one side of the center of rotation of the spindle, the said pin or stud serving to hold the said spindlesupport loosely on or With relation to the step-rail. l

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses. Y

WILLIAM fr. CARROLL.
